Abstract
Effect of coherence resonance in a heterogeneous array of coupled Fitz Hugh-Nagumo neurons was studied. The nontrivial effects of parameter inhomogeneity and spatial independence of noise on array-enhanced coherence resonance were considered. An increase in coherence was observed as the spatial correlation of noise decreased, and inhomogenity in the array parameters were found to enhance the coherence. The above factors were found to play a constructive role in enhancing the time precision of firing in neural systems.
